It is wildly harmful and an escalation of monstrous practices to look at one or several unjust actions and/or sentences and declare that those who do worse than the person who was dealt out such a retribution should receive an even longer sentence.
If someone gets 10 years for smoking weed, the solution is not to put someone in prison for 20 years for punching someone.
I wasn't implying that either Ulbricht or Madoff's sentences were unjust.
On the same principle, noting that someone who punched someone got one day in jail is not a good justification for why someone shouldn't get two days in jail for smoking weed.
